If you'd like, I'll keep you 
company all night long.
.إن أردت، سأرافقك طوال الليل
Wenn du magst, bleibe ich auch
die ganze Nacht bei dir.
Si quieres,
te haré compañía toda la noche.
Si quieres,
te haré compañía toda la noche.

Se vuoi, posso farti compagnia tutta la notte.
Se quiser, eu faço
companhia ao longo da noite.
Если хочешь, я составлю
тебе ночью компанию.
